CAMPAIGN INSTRUMENT.

SPECIFICATION forming part of Letters Patent No. 785,874, dated March 28, 1905.

Application filed June 2. 1904;. Serial No. 210,774.

To (tZZ whom, it may concern:

Be it known that I, ALEXANDER H. GOULD, I a citlzen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Campaign Instruments; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

5 My invention relates to instruments of the class more especially designed for use at election campaigns, parades, field sports, and analogous events, at which time noisy demonstrations by the people is in vogue.

The object of my invention is to provide an instrument of this character of cheap and simplified construction, that is adapted to be operated by hand instead of lung power, and at the same time will emit a harsh shrill noise 5 similar to that of campaign-horns.

The invention is fully described in the following specification and shown in the accompanying drawings, in which- Figure 1 is aperspective View of an instru- 3 ment embodying my invention. Fig. 2 is a central longitudinal section thereof, and Fig. 3 is a modified form of the same.

Referring to the drawings, 1 represents a bulb or chamber, which has a flanged noiseemitting opening 2 provided therein, and 3 a horn or megaphone, which has its contracted end secured to the flange of said opening 2 and is adapted to direct and throw the sounds made by the instrument. The bulb or cham- 4 her 1 is shown as comprising the top section a, in which the opening 2 is located, and the lower section 5, which latter is adapted to have its upper edge telescoped within the lower portion of the top section A or otherwise suitably secured thereto. Disposed diametrically within the bulb 1 is a diaphragm 6, which is securely held between the adjacent alining portions of the sections 4 and 5, as shown, and is composed of metal or other ma- '6 and has one end provided with a crank-arm 10, by means of which it is turned to rotate said disk.

In order to attain the best results in the op- 5 eration of my invention, it is necessary to employ a light flexible wire for the shaft 10 to enable it to have a vibratory movement as the teeth of the disk 8 move in and out of engagement with the rib 9, as otherwise a rapid ro- 7 tation of said disk would be prevented and less noise produced by the contact of the disk with the rib on the diaphragm.

IVhile the preferable mode of constructing my invention consists in the placing of the diaphragm 6 within a chamber, as shown in Figs. 1 and 2, more noise being derived from such construction, it is apparent that the same might be made in numerous ways, one of which is shown in Fig. 3 of the drawings. In this construction the noise-diaphragm a. comprises the base of the bulb or chamber 7), and the toothed engaging disk 0 is disposed between said diaphragm and the noise-outlet opening (Z, thus emitting more of a deadened 5 sound than the other construction. It is also obvious that such changes in the form, proportion, and minor details of construction of the parts as fairly fall within the scope of my invention may be made without departing 9 from the spirit or sacrificing any of the advantages thereof.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

An instrument comprising a chamber having an opening therein a diaphragm secured within said chamber, a rib on said diaphragm,

In Witness whereof I have hereunto signed my name to thls speclfioatlon in the presence IO of two subscrlbmg \vltnesses.

ALEXANDER H. GOULD.
